Which formula can be used to describe the sequence? f(x + 1) = –2f(x)
f(x + 1) = Negative one-halff(x)
f(x + 1) = One-halff(x)
f(x + 1) = 2f(x)

Step-by-step explanation:

what sequence ? we can't see it. so, there is no way to tell which answer is right.

nice answer

Step-by-step explanation:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
